To prevent possible SEVERE INJURY or DEATH:
• Install a LiftMaster Monitored Entrapment Protection (LMEP)
Device.
• NEVER permit children to operate or play with door control
push buttons or remote controls.
• Activate door ONLY when it can be seen clearly, is properly
adjusted and there are no obstructions to door travel.
• ALWAYS keep door in sight until completely closed. NEVER
permit anyone to cross path of closing door.
OPEN MID STOP
Feature: The Mid Stop feature is to open the door to a preset
point prior to the fully open position.
Benefit: The door opens to a midpoint between open and close
reducing heating and cooling costs. The door will not cycle fully,
providing longer door and operator life.
To Program:
1. Close the door.
2. Turn selector dial to PROG.
3. Press and release the MID button on logic board.
4. Press the OPEN button, wait until the door reaches the desired
mid stop height, then press and release the STOP button.
5. Press and release the MID button to complete programming.
6. Turn selector dial back to desired wiring type.
NOTE: A momentary open command will open the door fully from
the Mid Stop position. Once at the Mid Stop, photoelectric sensors
and other entrapment protection devices will not open the door
beyond the mid stop position, except in E2 mode. The Timer-To-
Close will work from the Mid Stop.
To clear the Mid Stop set the selector dial to PROG and press and
hold the MID button for 5 seconds. The MID LED will flash rapidly
and turn off once the Mid Stop has been cleared. Turn selector
dial back to desired wiring type.
TIMER-TO-CLOSE
Feature: Timer automatically closes door after preset time. All
entrapment protection devices must be unobstructed.
Benefit: The door will automatically close after preset amount of
time. Great for apartment buildings, fire stations and other
applications where the end user wants the door to close
automatically after a specified amount of time.
Requirements: Must have at least one LiftMaster Monitored
Entrapment Protection (LMEP) Device installed (refer to page 12).
